Since the beginning of March, the plastics market has experienced a rollercoaster ride: in the early days, driven by multiple factors, prices of mainstream products such as PE, ABS, and PC soared, triggering a frenzy of panic buying; however, on March 11, this frenzy came to an abrupt halt, with plastic prices falling sharply across the board. Core products like ABS and PE saw astonishing single-day declines, and the previously inflated price bubble quickly deflated, with the market returning to rationality. For those working in the plastics industry chain, this rapid rise and fall not only tested their financial strength but also their professional skills and mindset in dealing with market fluctuations.

I. Plastic Prices Return to Rationality on March 11: Four Core Factors Resonate The sharp correction in plastic prices on March 11 was the result of the convergence of four factors: crude oil price fluctuations, geopolitical sentiment, supply and demand dynamics, and market behavior. Essentially, it was a return of prices to the true supply and demand fundamentals after the previous market speculation subsided.
(I) Core Trigger: Crude Oil Plunge Causes Complete Collapse of Cost Support
As a core downstream product of the petrochemical industry, plastic prices are deeply tied to international crude oil prices, which are considered the "cost barometer" of the plastic market. On March 11, the international crude oil market experienced a precipitous drop, staging an extreme "overnight reversal." This sharp decline in crude oil directly led to the complete collapse of cost support for plastics. Following this, domestic petrochemical companies lowered their ex-factory prices, and spot market traders followed suit. The cost premium previously incurred due to rising crude oil prices was quickly wiped out, becoming the most direct driving force for the return of plastic prices to rationality.
(II) Key Trigger: Geopolitical Sentiment Subsides, Supply Panic Dissipates
One of the core drivers of the earlier surge in plastic prices was supply concerns triggered by geopolitical conflicts in the Middle East. Previously, the escalation of the conflict between Iran and Israel significantly increased shipping risks in the Strait of Hormuz, leading to widespread market expectations of a disruption in global oil and chemical supplies. Coupled with the impact of stagnant Iranian exports, speculative funds seized the opportunity to drive up plastic prices irrationally. However, on March 11, the geopolitical situation eased significantly, and news emerged that the G7 planned to release strategic oil reserves, completely alleviating market panic regarding energy supply disruptions. The price bubble created by geopolitical factors lost its support, and market expectations returned to rationality.
(III) Root Cause: Supply-Demand Imbalance Becomes Prominent, Downstream Resistance to High Prices Suppresses Price Increases
The long-term price trend is ultimately determined by supply and demand fundamentals. The earlier surge did not change the core contradiction of supply-demand imbalance in the plastic market. Downstream demand did not keep pace; orders from end-user industries such as home appliances, automobiles, and 3C products were weak, and resistance to high-priced raw materials was evident. The recent surge in plastic prices significantly increased costs for downstream injection molding, extrusion, and sheet/bar processing companies. Some even faced the predicament of "loss upon receiving orders," leading to a reduction in purchases and a focus on small, immediate orders to meet basic needs, resulting in sluggish market transactions. This supply-demand imbalance rendered the previous price increases unsustainable, making the March 11th correction inevitable, with prices returning to a reasonable range where supply and demand are aligned.
(IV) Market Drivers: Short-Selling by Traders Exacerbates the Correction
During the earlier surge in plastic prices, a large amount of speculative capital and traders followed the trend, hoarding and further amplifying the price increases. However, on March 11th, with the sharp drop in crude oil prices and the easing of geopolitical tensions, the market sentiment shifted dramatically. Speculative capital that had previously chased the price increases closed out their positions, and traders, realizing the market reversal, began selling off their inventory to realize profits and avoid further losses. The influx of spot goods into the market caused price chaos, and traders lowered prices to facilitate transactions, further exacerbating the price correction and pushing the market back from "frenzy" to "rationality." It is worth noting that the prices of semi-finished products such as plastic sheets and rods have also decreased in tandem with raw materials, leading to a strong wait-and-see attitude among processing enterprises and further reflecting rational market expectations.
II. What to do in the face of huge fluctuations in plastic prices?
1. Abandon speculative mentality and adhere to the principle of purchasing only what is needed.
2. Closely monitor key influencing factors and make accurate market predictions.
3. Optimize inventory management and reduce the risk of capital tied up.
4. Improve cooperation mechanisms and lock in costs and profits.

5. Strengthen internal capabilities and enhance core competitiveness.
